About Gary Duncan

He was guitarist with The Brogues, then most notably with Quicksilver Messenger Service, where the complex interplay between himself and fellow-guitarist John Cipollina did much to define the unique sound of that San Francisco based band. It was with the Brogues that he adopted the stage name Gary Duncan. It was in 1965 when, as Gary Cole, he joined the Brogues, in Merced, California, and met future Quicksilver Messenger Service drummer Greg Elmore.
